Ok, just a reminder, please have adb all set up on your pc, and make sure you've downloaded and installed the samsung vitality drivers. Also, I have no clue if this process erases all of your data. I only came upon this method because I had bricked my phone, and in my attempt to bring it back to working condition, I achieved full root with tethering abilities. You'll need to download "ODIN + OPS" and "SCHR720_EH02_Prerooted-PDA" https://www.asuswebstorage.com/navigate/share/YY4FNYKNA http://oeo.la/GY4YY7YSX4 Download and run the Odin program. It will ask to load "OPS". OPS is contained in same folder as Odin. On the bottom right you'll see buttons such as "Phone" and "PDA" etc etc. On the PDA section, click the button to load "PDA" and direct it toward the "SCHR720_EHO2_Prerooted-PDA" folder. Once you have those files loaded, you must load your phone into download mode. After much trial and error, and a lot of searching, I found the best way for my phone was to make sure it's turned off and unplugged from computer. Then you hold down the volume down button, hold down the Muve music button, then plug the phone into the computer's usb port. Keep holding down both the volume down and Muve button for 3 seconds, then release the volume down button while still pressing in the Muve button. You'll see a screen asking if you'd like to continue, press the volume up button to enter into download mode. You should see a notification on your Odin that a device has been connected, you may now press "Start" on Odin and sit back and watch the magic happen. Once it's done, you can start up as usual, and you'll likely have no service, then you'll have "metro pcs service" but your phone number will be some odd 999 number. Open up your dial pad and press *228 then press send or call. The phone will then call cricket and begin programming your phone for use on cricket network. Upon completion you'll see your data come back to life ( you may need to restart phone) Link your google account, then make sure you have super user installed, if not, just download it from market. Next step is to download titanium to check your root and remove bloatware, then bam, download wifi tether for root users, and you have a fast, responsive, bloat-free, tethering money saver. In the end I have android 2.3.4, baseband s:r720.06 x.eh29 kernel 220.127.116.11 build number GINGERBREAD.EH02 I'll post a link to the pre-rooted rom in a bit, but you might be able to google search it and download it from where ever I downloaded it by then. *edit* Please note I did NOT create or code any of this. This is all made possible to you by the awesome people who worked hard to make these softwares for us to download and try to use.
